Defeating the paladin is easy, just go on the defensive with occasional attacks so he'll heal, he can't recharge focus, and healing takes a large portion of it, so just make him lose all his focus, then attack, and it'll be easy.
I am getting so effing TICKED!! None of the games will load anymore! (sorry if this is irrelevant to the game, but in a way it's relevant because I can't even play it.) Specifics are that it just remains as the initial gray box. and after it's done loading (the window) then the game-window is still gray. So everything else is loaded, except the game-window.
